Answer 4

graph the function and tell me what the smallest root is

Answer 5

you can click the root to see what number it is

Answer 6

Correct

Answer 7

the nearest integer below that is 0

so 0 is indeed the lower bound of the roots

Answer 8

lower bound = left boundary

Answer 9

4 is the closest upper bound, but 5 is also an upper bound

Answer 10

since all of the roots are below 5

Answer 11

it's not x^6, it's just 6 since thats the largest exponent
